In reply to efrance24234:
There are plenty of deals at the mo, although they tend to be light- and mid-weight jackets: Blacks and The Epicentre both have sales on (I got a Sherpa Dengboche jacket - lightish - from The Epicentre for sixty five quid, which is a ridiculous bargain).
Alternatively, sportspursuit turn them up regularly, provided last year's colours aren't too embarrassing to be seen in.
